Abstract
Genetic cholestatic liver diseases are caused by (often rare) mutations in a multitude of different genes. While these diseases differ in pathobiology, clinical presentation and prognosis, they do have several commonalities due to their cholestatic nature. These Clinical Practice Guidelines (CPGs) offer a general approach to genetic testing and management of cholestatic pruritus, while exploring diagnostic and treatment approaches for a subset of genetic cholestatic liver diseases in depth. An expert panel appointed by the European Association for the Study of the Liver has created recommendations regarding diagnosis and treatment, based on the best evidence currently available in the fields of paediatric and adult hepatology, as well as genetics. The management of these diseases generally takes place in a tertiary referral centre, in order to provide up-to-date approaches and expertise. These CPGs are intended to support hepatologists (for paediatric and adult patients), residents and other healthcare professionals involved in the management of these patients with concrete recommendations based on currently available evidence or, if not available, on expert opinion.

Abstract
INTRODUCTION Alpha 1 antitrypsin deficiency (A1ATD) accounts for 21% of all pediatric liver transplants due to metabolic disease in the western world. Donor heterozygosity has been evaluated in adults but not to a recipient with A1ATD. METHODS The data of patient were retrospectively analyzed and a literature review performed. RESULTS We present a unique case of living related donation from a A1ATD heterozygote female to a child for decompensated cirrhosis due to A1ATD. In the immediate postoperative period, the child had low-alpha 1 antitrypsin levels, but these normalized by 3 months posttransplant. He is currently 19 months post-transplant with no evidence of recurrent disease. CONCLUSION Our case provides initial evidence that A1ATD heterozygote donors may be safely used for pediatric patients with A1ATD, thus expanding the donor pool.

[PMID: 34408830 PMCID: PMC8367211 DOI: 10.1177/20406223211002988] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 02/24/2021] [Indexed: 11/23/2022] Open
Abstract
Alpha-1 antitrypsin (AAT) augmentation is effective in slowing the progression of
emphysema due to AAT deficiency (AATD) but cannot prevent eventual progression
to end-stage lung disease and complete respiratory failure, which is the leading
cause of death for individuals with severe AATD. When patients develop end-stage
lung disease, lung transplantation is the only treatment option available, and
this can improve lung physiology and patient health status. The available data
suggest that survival rates for lung transplantation are significantly higher
for patients with AATD-related chronic obstructive pulmonary disease (COPD)
compared with non-AATD-related COPD, but, conversely, there is a higher risk of
common post-lung transplant complications in patients with AATD
versus non-AATD COPD. Nevertheless, lung transplantation
(single and bilateral) is favorable for patients with AATD. After respiratory
failure, the second leading cause of death in patients with AATD is liver
disease, for example, cirrhosis and hepatocellular carcinoma, caused by the
accumulation of mutant forms of AAT retained within the liver. As with lung
disease, the only treatment option for end-stage liver disease is liver
transplantation. Survival rates for patients with AATD undergoing liver
transplantation are also favorable, and patients, particularly pediatric
patients, have benefitted from advancements in peri-/post-surgical care. As the
majority of AAT is produced by the liver, the AAT phenotype of the recipient
becomes that of the donor, meaning that AAT serum levels should be normalized
(if the donor is AAT-replete), halting further lung and liver disease
progression. However, post-liver transplant respiratory function may continue to
decline in line with normal age-related lung function decline. In the most
severe cases, where patients have simultaneous end-stage lung and liver disease,
combined lung and liver transplantation is a treatment option with favorable
outcomes. However, there is very little information available on this procedure
in patients with AATD.

Abstract
ABSTRACT Metabolic liver diseases (MLDs) are a heterogeneous group of inherited conditions for which liver transplantation can provide definitive treatment. The limited availability of deceased donor organs means some who could benefit from transplant do not have this option. Living related liver transplant (LrLT) using relatives as donors has emerged as one solution to this problem. This technique is established worldwide, especially in Asian countries, with shorter waiting times and patient and graft survival rates equivalent to deceased donor liver transplantation. However, living donors are underutilized for MLDs in many western countries, possibly due to the fear of limited efficacy using heterozygous donors. We have reviewed the published literature and shown that the use of heterozygous donors for liver transplantation is safe for the majority of MLDs with excellent metabolic correction. The use of LrLT should be encouraged to complement deceased donor liver transplantation (DDLT) for treatment of MLDs.

Abstract
Alpha-1 antitrypsin (AAT) deficiency is a common inherited metabolic disorder caused by a point mutation in the SERPIN1A gene. A small portion of homozygous PI*ZZ individuals develop severe liver disease that requires liver transplantation. Posttransplant survival is excellent. The largest burden of advanced liver disease lies within the adult population rather than children. Evaluation of lung function in adults before transplant is essential because of the underlying risk for chronic obstructive pulmonary disease. Post-liver transplantation lung function should also be monitored for decline. Although uncommon, cases of simultaneous lung and liver transplant for AAT deficiency have been reported.

Abstract
It is well recognized that solid organ transplantation can transmit bacterial infection and chronic viral hepatitis as well as certain cancers. As indications for liver transplantation (LT) have expanded, it has been used to treat and even cure certain genetic cholestatic disorders, urea cycle defects, and coagulation abnormalities; many of these conditions are potentially transmissible with LT as well. It is important for clinicians and transplant patients to be aware of these potentially transmissible conditions as unexplained post-LT complications can sometimes be related to donor transmission of disease and thus should prompt a thorough exploration of the donor allograft history. Herein, we will review the reported genetic, metabolic, hematologic, and immunological disorders that are transmissible with LT and describe clinical scenarios in which these cases have occurred, such as in inadvertent or recognized transplantation of a diseased organ, domino transplantation, and with living related liver donation.

Abstract
The efficient generation of hepatocytes from human pluripotent stem cells (hPSCs) requires the induction of a proper endoderm population, broadly characterized by the expression of the cell surface marker CXCR4. Strategies to identify and isolate endoderm subpopulations predisposed to the liver fate do not exist. In this study, we generated mouse monoclonal antibodies against human embryonic stem cell-derived definitive endoderm with the goal of identifying cell surface markers that can be used to track the development of this germ layer and its specification to a hepatic fate. Through this approach, we identified two endoderm-specific antibodies, HDE1 and HDE2, which stain different stages of endoderm development and distinct derivative cell types. HDE1 marks a definitive endoderm population with high hepatic potential, whereas staining of HDE2 tracks with developing hepatocyte progenitors and hepatocytes. When used in combination, the staining patterns of these antibodies enable one to optimize endoderm induction and hepatic specification from any hPSC line.

Abstract
PI*ZZ alpha-1 antitrypsin (AAT) deficiency poses risk for lung disease through 2 different mechanisms: a toxic loss of function in which deficient AAT levels cause a depleted proteolytic screen and, separately, a proinflammatory effect of Z polymers produced both by alveolar macrophages and by the liver. Ample data support the first mechanism, while the possible contribution of the second 2 proinflammatory mechanisms is currently unknown. Experience with a 74 year-old PI*ZZ female who underwent single lung transplantation and subsequent orthotopic liver transplantation (OLT) may shed light on the relative contributions of each of the potential mechanisms. Availability of multiple pulmonary function tests (PFT) measurements uniquely permitted calculation of rates of lung function change before and after OLT. The rate of forced expiratory volume in 1 second (FEV1) decline normalized post-OLT (from -60 to -21 ml/yr). Her course suggests that restoring the normal serum AAT levels or, alternately, eliminating liver-derived polymers, exerted a greater effect on preventing emphysema progression than local Z polymer production contributed to furthering emphysema.

Abstract
Metabolic diseases that involve the liver represent a heterogeneous group of disorders. Apart from the metabolic defect, the subject's liver functions may be normal. With the increasing need for organs, livers from donors with metabolic diseases other than familial amyloid polyneuropathy might be possibly used for transplantation. However, whether such livers qualify as grafts and how they might impact recipient outcome are still unanswered questions. This review of the literature summarizes current experience in the use of such grafts in the context of cadaveric, domino, and living-related liver transplantation.
